Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581556, here are decompositions:

163 + 33581393 = 33581556
227 + 33581329 = 33581556
257 + 33581299 = 33581556
269 + 33581287 = 33581556
277 + 33581279 = 33581556
293 + 33581263 = 33581556
347 + 33581209 = 33581556
409 + 33581147 = 33581556

Showing the first eight; more decompositions exist.
